Initial caloric administration as a risk factor for mortality in critically ill children
Background: The mortality rate of critically ill children with multiple organ dysfunction syndrome (MODS) in Indonesia is approximately 51.85%. Various studies suggested malnutrition as a risk factor for mortality; therefore, nutrition therapy in the form of initial caloric administration became imperative.
Objective: To determine the relationship between initial caloric administration (initial route, initial time and the fulfilment of caloric requirement) and mortality of critically ill children.
Design: Case-control study.
Setting: The Pediatric Intensive Care Unit (PICU) of Dr. Sardjito General Hospital Yogyakarta in 2015.
Patients and participants: Children aged 1 month to 18 years old hospitalized in the PICU for at least 4 days in 2015. Subjects were divided into case group (non-surviving patients) and control group (surviving patients).
Measurements and results: We used McNemar test and stepwise conditional logistic regression for data analysis. From 102 subjects (51 in each group), the proportion of malnourished children in the case group was higher than in the control group (58.8% and 29.4%, respectively). Parenteral route and lack of caloric achievement within the 3rd to 6th day of hospitalization significantly increased the risk of mortality (p<0.05) with ORs of 13 (95%CI 1.95 to 552.47), 3.8 (95%CI 1.37 to 13.02), 4.25 (95%CI 1.39 to 17.26), 4.00 (95%CI 1.08 to 22.09), and 10.0 (95%CI 1.42 to 433.98), respectively. Caloric initiation after the first 48 hours of hospitalization did not significantly affect the mortality rate (p>0.05). Confounding variables that affected mortality include the severity of disease, use of ventilator, hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), and malnutrition (p<0.05). Multivariate analysis revealed that parenteral route and malnutrition significantly influenced mortality with ORs of 36.05 (95%CI 3.22 to 404.13) and 9.04 (95%CI 2.09 to 39.19), respectively.
Conclusion: There is a relationship between route of initial caloric administration and mortality of critically ill children, where parenteral nutrition significantly influenced mortality in critically ill children.
